Manfrotto 055XPROBI bought this tripod to use while I was getting repairs to my 190X PROB.
It's as steady as they come at this weight and price and holds everything I've put on it.
I use a Manfortto 804RC2 pan head on this one.
With a heavy lens you are limited to how far out you can set the post while horizontal. It will teeeter if it's out too far.
In spite of it's size, it will get down as low as the 190, and is great for macro work.
I'm about 5' 9" and need a step ladder to use it with the column extended, if you're on the tall side you will love it.
